A positioning mark apparatus of a surgery navigation system and an implementation instrument thereof are disclosed. The positioning mark apparatus includes a positioning base and a frequency modulated radio frequency positioning module. One end of the positioning base is a lock portion having a screw structure, another end is a head having a joint structure, and a free end of the head has a fitting structure. The frequency modulated radio frequency positioning module has a sleeving structure that cooperates with the head structure and buckles with the joint structure. The frequency modulated radio frequency positioning module includes an antenna unit, a printed circuit board unit electrically connected to the antenna unit, and an electronic component battery unit supplying power to the printed circuit board unit. The frequency modulated radio frequency positioning module may transmit, according to a received frequency modulated signal, a feedback signal including a radio frequency signal to the external.

A sensing apparatus is applicable to a surgical instrument having a clamping portion, a linkage rod member and an operating portion. The damping portion is used to damp a target. The sensing apparatus includes a touch sensor set, a force sensor, a displacement sensor and a processing device. The touch sensor set can sense a touch signal between the target and the clamping portion. The force sensor can sense a clamping force applied on the target. The displacement sensor can measure a displacement of the linkage rod member. The processing device includes a database, a processing unit and a comparison unit. The database stores reference curves of different reference objects. The processing unit can build an actual measurement curve of the target. The comparison unit can compare the actual measurement curve with each of the reference curves to obtain one of the reference curves corresponding to the actual measurement curve.

A microfluidic chip for three-dimensional cell culture with high-throughput perfusion includes an array of cell culture units, each unit including a cell culture medium inlet hole connecting to one cell culture medium tank, at least one micro-bioreactor, at least one microchannel and at least one medium collection and analysis tank. Each medium collection and analysis tank is connected to an air chamber with an air channel and the air chamber has negative pressure source holes to generate negative pressure to drive the culture medium. The microfluidic chip also includes an intermediate plate connected to the bottom surface of the roof, and two bottom plates detachably assembled at the bottom of the intermediate plate. The first and second bottom surfaces have micro-bioreactors and cylindrical recessed slots and the intermediate plate has corresponding holes to achieve the goal of three-dimensional cell culture using minimum experimental resources with high-throughput perfusion.

A computer executable tool analyzes unknowns (Xs) in gate-level simulation and traces their sources to determine if the Xs are generated due to X-pessimism. For Xs generated due to X-pessimism, fixes are generated to correct simulation results. Corrected simulation results match real hardware behavior and greatly reduce the analysis effort of engineers.

An apparatus for high-throughput cell culture with mechanical compression stimulation includes a cell culture vessel and a fluid pressure supply unit. The cell culture vessel includes at least one culture chamber, at least one pressure chamber disposed above the culture chamber, a membrane disposed between the culture chamber and the pressure chamber, and at least one pressurizing member that projects downwardly from the membrane into the culture chamber. The fluid pressure supply unit is connected fluidly to the pressure chamber, and has a fluid pressure supply device to supply a pressurized fluid to the pressure chamber so as to deform the membrane and move the pressurizing member, and a control device that is adapted to vary a pressure of the pressurized fluid in the pressure chamber.

A retention synthesis application provides a means of analyzing a circuit design, functional test sequences, and the associated power specification to identify registers that do not need retention when a block is powered down. Reducing the number of retention registers reduces power consumption and chip area. The retention synthesis application is based, at least in part, upon symbolic simulation. In symbolic simulation, a symbol is used to represent a value that can be either 0 or 1 and the propagation of symbols is traced through the simulation.

This invention provides a system and method for correcting gate-level simulation commences by identifying unknown values (Xs) that are falsely generated during the simulation of a given trace for a design netlist. Then, a sub-circuit of the design netlist is determined for each false X that has inputs of real Xs and an output of a false X. Finally, simulation correction code is generated based on the sub-circuit to eliminate false Xs in simulation of the design netlist. The original design netlist can then be resimulated with the simulation repair code to eliminate false Xs. This allows gate-level simulation to produce correct results.
